12 Claims, 11 Drawing Figures PATENTED AUG 74 SHEEI 1 0r 3 PATENTED 61974 3.8279202 SHEEI 2 0P3 JOINT FOR ENCLOSURE, AND MOUNTING THEREFOR BACKGROUND OF THE INVENTION This invention relates in general to sheel metal enclosures for air conditioning equipment and deals more particularly with an enclosure system which provides dimensional installation flexibility and which may be prefabricated in a factory to be quickly and easily assembled on the job, and yet provide an architecturally pleasing appearance.

Problems arise during the installation of prefabricated metal enclosures in buildings due to normal building tolerances between, the floor, ceiling and the wall mounting surfaces. Difficulties invariably arise at the job site when panel sections must be cut to fit. The neat installation envisioned by the architect may not be achieved due to the lack of attention to these tolerances on the part of the enclosure designer.

The general aim of the present invention is to provide an enclosure which incorporates an adjustable mounting system which would absorb building tolerances in the area of installation.

Another aim of the invention is to provide a unique panel joint system of cover battens and structural mullions which form a convenient panel joint capable of assembly in the field, while giving a custom architectural appearance after assembly.

SUMMARY OF THE INVENTION In accordance with the present invention an enclosure is provided wherein structural mullions are adjustably fastened, at spaced locations to floor, ceiling or wall mounted support brackets. Sheet metal panels are then supported by and fastened to the mullions by a unique system of cover battens and spring clips.

The panel joining system, by means of which the panels are secured to the mullions with cover battens in accordance with the present invention comprises battens having finished outer surfaces, and structural mullions fastened to the battens by spring clips, which clips are adapted to releasably engage channels defined by the mullions.

An adjustable mounting system is also provided by means of which one end of each mullion is attached to the floor or ceiling mounted support bracket and the other end to a wall mounted support bracket. The floor or ceiling system utilizes an angle plate and an anchor plate through which the mullion and bracket are joined by a bolt and nut. A vertical slot in the angle plate allows the structure to be anchored at the desired height above the floor. An oblique slot in the anchor plate facilitates and helps hold the height adjustment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning first to FIG. 1, a wall and floor mounted enclosure is indicated generally at 10. This enclosure includes an extruded wall support bracket 20 which is fastened to the wall W and a floor support bracket 40 secured to the floor F. Structural mullions 30 are bolted to these support brackets at spaced locations along the length of the structure. The enclosure panels 50, 51 are set in place and secured to the mullions by means of cover battens 33. The battens in turn are held to the mullions by a number of spring clips 34. The juncture of two adjacent enclosure panels such as 50 and 52 and also 51 and 53 determines the location of the mullions. In this way a panel may be cut to any desired length and securely fastened at its ends to mullions.

An alternate type of enclosure is indicated generally at 12 in FIG. 2. This enclosure 12 utilizes two wall support brackets 20 as shown and requires no floor mounted brackets as shown at 40 in FIG. I. Mullions 30a are then battened to these supports 20 and the enclosure is formed in much the same manner as the structure of FIG. 1.

FIG. 5 illustrates a detailed cross section of the wall and floor mounted enclosure of FIG. 1. Considering FIG. 4 in greater detail, the wall support bracket 20 is seen to be of extruded metal, and is fastened to the wall W by a number of screws 22 which pass through a row of regularly spaced holes provided at intervals along the length of the bracket and adapted for this purpose.

The support bracket includes a integral slotted channel 20a along its top edge in which may be trapped a number of mullion mounting bolts 24. The shanks of the trapped bolts project upwardly through the slot thus allowing the bolts 24 to be positioned along the length of the bracket for securing one end of the mullion 30 to the bracket 20. The bracket 20 also includes a groove 20b from which air conditioning equipment (not shown) can be conveniently mounted.

A detailed cross section of the enclosure panel joint assembly is shown in FIG. 3. Two adjacent panels 50 and 52 are set in place atop the mounting flanges 31 and 32 of the mullion 30. A cover batten 33 is then supported into the mullion channel 30a by means of spring clips 34 thereby anchoring the panels in position by forcing them against the mullion flange.

The battens are more particularly joined to the mullions by these spring clips 34, which spring clips are forced into and releasably retained within the mullion channel 30a. A number of these clips are fastened to each batten by bolt means in the form of threaded screws and nuts, 36 and 37 respectively. The heads of these bolts are retained within a channel 33a which is integral with the rear wall of the batten and which extends the length of the batten. The shanks of the bolts protrude through a slot in the rear wall of the channel thus permitting the bolts to be moved within the channel for positioning anywhere along the length of the batten. In this way a suitable number of clips may be spaced as needed along the length of the batten to insure a strong joint between it and the mullion.

The above described enclosure joint construction is well suited for joining panels of various geometric configurations. The enclosures shown in FIGS. 1 and 2 illustrate two presently preferred embodiments, but other enclosure shapes might also be devised to take advantage of the joint shown in FIG. 3. In addition, the joint structure of FIG. 3 may assume alternate configurations. Two such configurations are shown in FIGS. 8 and 9. Both of these configurations can utilize a mullion having a rectangular channel and in the case of FIG. 8 the spring clip 34 has been eliminated and the bolt 36a allowed to pass through the base of the mullion channel and to be releasably retained by a wing nut 37a. The configuration of FIG. 9 avoids the use of a bolt by directly entrapping the head portion of the spring wire clip, the leg portions of which pass through holes in the mullion channel to secure the clip therein.

Referring more particularly to the FIG. enclosure shape, the mullion 30 is formed from several straight sections, or portions which portions may be welded or otherwise connected at the corners A and B to provide the generally L-shaped frame of FIG. 5. The batten 33 is then bent to shape as required, and provided with the spring clips 34 at selected locations to permit the final assembly on site.

In the FIG. 5 enclosure the top mullion portion supports at least one top panel 50, and said top panel may include a depending flange 50a for supporting a louvered insert panel (not shown). The enclosure of FIG. 5 also includes at least a front panel 51 which is bent at the corner A to provide a horizontally oriented top segment 51a and a vertically oriented front segment 51b. The top segment has a depending flange similar to that shown at 50a to support the louvered insert panel.

FIGS. 6 and 7 illustrate the means by which the enclosure is adjustably mounted on the floor support bracket 40. The extruded floor support bracket 40 is fastened to the floor F by convenient means as for example by the wood screws 41 which pass through regularly spaced holes in the lower leg of the support. Thus mounted the upper leg of the support is generally vertical with respect to the floor and forms a base and kickspace under the enclosure.

A slotted rearwardly opening channel 40a is integrally formed along the top edge of the vertical support bracket leg. This channel 400 is adapted to receive and retain the heads of a number of mullion mounting bolts 46. The slot in the rear wall of the channel permits the shanks of the bolts to protrude rearward and permits the bolts to be moved within the channel to any desired location along the length of the support bracket 40.

The lower end or return leg of the mullion 30 is oriented horizontally and at right angles to the floor mounted support bracket 40. This return leg is fastened to the floor support bracket by means of an angle plate 44, and an anchor plate 42. The angle plate is permanently joined, by one of its legs, to the end of the mullion either by spot welding or other suitable means. The other, or depending leg of the angle plate extends downwardly and has a vertically elongated slot 44a. The slot 44, best shown in FIG. 7, is adapted to permit the shank of the mounting bolt 46 to pass through the angle plate and to be vertically adjustable therein. The bolt is then secured by a nut 47.

The anchor plate 42, when installed, is trapped between the angle plate 44 and the rear wall of the slotted channel 40a. The lower edge of the anchor plate is set in a groove 40b which is integrally formed in the lower leg of the floor support bracket 40 and which extends along the length of the bracket. The entrapped upper portion of the anchor plate includes an obliquely oriented slot 42a adapted to allow the shank of the mounting bolt 46 to pass through the anchor plate before passing through the vertical slot in the angle plate 44.

The vertical slot 44a in the angle plate 44 allows the height of the enclosure to the floor support bracket to be adjusted to accommodate any building tolerances between the floor and wall. The oblique slot in the anchor plate facilitates and holds this height adjustment without having to overtorque the nut 47, or use lock washers or the like.

The adjustable floor mounting system first described may also be utilized in the ceiling mounted enclosure illustrated in FIG. 10. As shown, the components of the ceiling mounted application are identical as is the adjustment procedure.

Still another application of the adjustable mounting system is shown in FIG. 11 which illustrates a freestanding floor mounted enclosure. In this case two sets of components are utilized to adjust the height of the structure above the floor. This also allows the enclosure to compensate for a sloping floor by maintaining a level appearance.
